What Do You Think Goes Into Developing Games?

Consider a video game you want to build (or, one you like that has been built)

Assume you are inspired (or forced or paid) to engineer the game

Take 3-4 minutes to write a list of the tasks required Chronological or hierarchical, as you wish Include your name and name of game

What do we have?

Developed a couple of games: Tag Volleyball Ping Pong

Together with Bill Harrison Created the Light Gun

Photodiode Senses light on screen

Screen blacks out Diode begins reception Portion of the screen is

painted white - typically the target you are aiming for

If diode senses black then white - hit!

Created Breakout Two firsts for the

industry: Software was used to

run a video game Breakout was

programmed in a computer language Previously, machine code

Shows the industry two things: Innovation is

important Merchandising!

Cereals TV-Shows T-Shirts…etc

History - 1980s1985

Nintendo Entertainment System Bundled with Super

Mario Brothers Dominated the North

American market D-pad now became

standard

History - The 1990sShareware

becomes popular because of: Doom Wolfenstein 3D Demo

First portion of the game

Good way to show off their game

Many companies mimicked id Software

History - The 1990s 1996

3dfx releases the Voodoo chipset

Quake was among the first to utilize standalone graphics cards

Devoted 3D rendering cards Allowed CPU to handle

other computations

History - The 1990s3D era

32 bit era brings 2 major consoles to consumers Sega Saturn Sony Playstation

After many delays… Nintendo 64 64 bit system Revolutionary system

History - The 1990sNintendo 64

1.5 million units sold in three months

Disciplines Game Physics Programmer AI Programmer Graphics Programmer Sound Programmer UI Programmer Input Programmer Network Programmer Game Tools Programmer Porting Programmer Lead Game Programmer

Disciplines - PhysicsDeveloping the

physics in the gameProcessor cycles

are at a premium Efficiency is key

FPS games typically demand large teams of physics programmers

Disciplines - AIDevelops the logic that the game usesHas developed into a specialized area as of

latePathfinding, strategy, and enemy tacticsAccording to Game Developer Magazine -

60% of timeReal time strategy and first person shooters

Disciplines - Graphics Programmers who specialize in

developing and modifying complex 3D graphics

2D graphics abilities are still useful though Cell Phones PDAs

Scarce in industry Demand high salaries

Disciplines - SoundFull musical scores - been around3D positional sound - recent

First person shooters Programmers try to include the

newest technologies Games with large soundtracks or

advanced audio, demand teams of sound programmers

Disciplines - User Interface Very important!

Must be intuitive, useful-feature, clean, and easy to use

Most user interfaces are 2D Some interfaces are developed with the

same 3D technology as the rest of the game

Advanced interfaces allow custom scripting

Disciplines - InputWrites code that

determines how the player will use the input devices Controller Joystick Keyboard & Mouse

Wii controller Motion sensing

technology

Disciplines - InputProgrammers must

recognize and adhere to controller standards WASD A (X) - accept // next B (triangle) - back //

cancel If standards are not

followed, gamers will be confused

Disciplines - Network Writes the code that

allows players to play the game on a LAN and or on the internet

Very important in Massively Multiplayer Online (MMO) Latency control is

especially important Programmers cannot

assume all consumers have broadband Must be efficient Might be dial-up gamers

Disciplines - Game ToolsWrite code to

handle tasks like scripting, converting art, batches, modifying the game and levels

Half-Life 2 Source SDK

Create levels (Hammer)

Facial animations

Today’s GameTools Alternative2D Games• GameMaker• Multimedia Fusion 2• Construct• Flixel• FlashPunk• Stencyl• Game Salad

3D Games (&2D Games)• Unity• UDK• XNA• BlitzMax• jMonkeyEngine• Torque

First, we wanna try this in workshop..

Disciplines - Porting Porting is very

important, especially for companies like EA Games available on

almost every platform May involve the tools

programmer to help convert content

Some code may have to be re-written to utilize different hardware

Disciplines - LeadKeeps the programmers focused,

and on trackQuite often a middle man between

the client and programmersShould have a general base

knowledge of all aspects of the game Sound Graphics Networking Etc.

The Game Implementation ProcessPrototypingGame DesignLanguageAPI & LibrariesProductionCrunch TimeMaintenance

Process - Prototyping Very similar to normal applications Test ideas and algorithms Give the customer and early glimpse Early screenshots

Good way to gain early popularity

Process - LanguageWhat language to

use? Many dependencies

Staff Platform Language of the game

engine

Most popular C++

Process - API & LibrariesWhich API & Libraries to use?

Tons of libraries out there Sound processing Input Graphics rendering Pathfinding

Also depends on target platform Libraries for PS2 may not be available for

XBOX360 Graphics API?

DirectX OpenGL

Process - API & Libraries A collection of APIs

Direct3D The 3D graphics API

Not portable Designed specifically for

Microsoft products Pocket PC XBOX Windows

Revised more frequently then OpenGL Utilizes the latest features

of 3D graphics cards

Process - API & LibrariesPortable 3D API

Easily ported to and from Windows <-> MacOS

<-> Linux

Revised infrequently

OpenGL Tutorial Recommendation: http://www.arcsynthesis.org/gltut/index.html

Process - Production Bulk of the time Code…code…code Design documents are constantly

changing Lead regularly reports status to

supervisor Develop game tools

Process - Crunch Time Towards the end of the production phase Productivity is not proportional to extra

hours 2x hours != 2x productivity

Adding extra staff may not increase productivity

Quality decreases as time increases

Process - Maintenance Console

Pre-current generation - next to impossible Hard drives and online- now possible

Patches and new content PC

Numerous hardware / software combinations Patches are inevitable

MMO Genre Extensive maintenance phase New content is always required

The Present and the Future of Gaming Multithreaded Gaming HD Gaming Next Generation

Present & Future - Threading Split up processes Games w/ multiple threads

Run more efficiently on HT or multicore processesors

XBOX 360 and PS3 Multiple processors

Present & Future – Game InterfaceSmart TVMotion CaptureEtc.
